How GPA Calculation Works
GPA (Grade Point Average) is a weighted average of your grades, where each course's grade is weighted by its credit hours. The formula is: GPA = Σ(grade points × credit hours) / Σ(credit hours).
On the standard US 4.0 scale: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0.0. Some schools use variations. A few don't have plus/minus grades, and some cap at 4.0 even for A+.
The "weighted" part matters. A 4-credit course affects your GPA twice as much as a 2-credit course. Getting an A in a 1-credit seminar doesn't offset a C in a 4-credit core course. This is why students sometimes strategically take lighter course loads in difficult semesters.
Cumulative GPA includes all semesters. Semester GPA is just one term. Most graduate school applications and employers care about cumulative GPA, though an upward trend in semester GPAs can partially offset a lower cumulative number.
When You Need a GPA Calculator
Planning your semester to maintain a target GPA
If you need a 3.5 cumulative GPA for your scholarship, you can calculate what grades you need this semester to stay above the threshold. Add your current courses and experiment with different grade scenarios.
Graduate school applications
Most grad programs list minimum GPA requirements (typically 3.0–3.5). Calculate your cumulative GPA to see where you stand, and figure out if your remaining semesters can bring it up enough.
Checking Latin honors eligibility
Cum laude typically requires 3.5+, magna cum laude 3.7+, and summa cum laude 3.9+ (varies by school). Calculate your projected final GPA to see which honor you're on track for.
GPA Tips
Credit hours matter more than number of courses
A single bad grade in a 4-credit course hurts more than two mediocre grades in 2-credit courses. When planning your schedule, consider the GPA risk of high-credit courses in difficult subjects.
Check if your school uses plus/minus grading
At schools without plus/minus, a B is a B whether you scored 80% or 89%. At schools with plus/minus, that 89% becomes a B+ (3.3 vs 3.0). This calculator supports both systems.
Pass/Fail courses don't affect GPA
Most schools exclude P/F courses from GPA calculation. If you're struggling in a course, switching to P/F (if allowed) protects your GPA. But some grad programs want to see letter grades in relevant courses.
Limitations
- Uses standard 4.0 scale (A=4.0, B=3.0, C=2.0, D=1.0, F=0). Does not support weighted GPA, 5.0 scale, or percentage-based systems.
- Does not handle plus/minus grades (A+, A-) by default — these vary by institution (some use 4.3 for A+, others cap at 4.0).
- Cannot import grades from transcripts or student information systems. All grades must be entered manually.
- Does not calculate Dean's List eligibility, Latin honors thresholds, or major-specific GPA — only cumulative GPA.

Frequently Asked Questions
What grading scale is used?
The standard US 4.0 scale: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0.0. Some schools give A+ = 4.0 (same as A), while a few award 4.3 for A+.
How are weighted credits calculated?
Each course's grade points are multiplied by its credit hours. A B (3.0) in a 4-credit course contributes 12.0 quality points. Your GPA is the total quality points divided by total credit hours attempted. This means higher-credit courses have proportionally more impact on your GPA.
What is a good GPA?
It depends on context. For most jobs: 3.0+ is fine, 3.5+ stands out. For graduate school: 3.3+ for master's programs, 3.5+ for competitive PhD programs. For medical school: 3.7+ is competitive. For law school: depends heavily on the school tier. Dean's list is typically 3.5+.
Can I calculate my GPA if my school uses a different scale?
This calculator uses the US 4.0 scale. If your school uses a 10-point or percentage scale, you'll need to convert your grades first. For example, on a 10-point scale: 9-10 ≈ A, 8-9 ≈ B, 7-8 ≈ C, etc.
Do transfer credits affect my GPA?
Usually no. Most US colleges accept transfer credits but don't include the grades in your GPA calculation at the new school. Your GPA starts fresh, though the credits count toward graduation requirements. Check your school's specific policy.
